Eight albino rats, conditioned to press a lever to escape shock, continued to lever press during short inescapable shocks presented subsequently. The rate of this behavior was found to be higher for higher shock intensities regardless of the order in which shock values were presented. Relative to the immediately preceding escape rate, responding during inescapable shock was higher following conditioning at higher fixed-ratio escape requirements. Four subjects not conditioned to escape shock pressed the lever very infrequently during inescapable shock and showed little change with changes in shock intensity. The escape conditioning effects suggest that responding during inescapable shock is superstitious escape behavior. The effects of shock intensity on this behavior appear to be similar to reported effects of shock intensity on escape behavior.
八只白化大鼠经过条件反射训练，学会按压杠杆以逃避电击，随后在短暂的不可逃避电击中继续按压杠杆。无论电击值呈现的顺序如何，该行为的速率都随着电击强度的增加而增加。与之前的逃避率相比，在较高的固定比例逃避要求下进行条件反射训练后，在不可逃避的电击中，反应率更高。四个未经过逃避电击条件反射训练的实验对象在不可逃避的电击中很少按压杠杆，并且随着电击强度的变化变化很小。逃避条件反射的效果表明，在不可逃避的电击中，反应是迷信的逃避行为。电击强度对这种行为的影响似乎与电击强度对逃避行为的影响相似。
